Ok so I have no need for this extra 25" tube that had a med res chassis on it. Will a tube that had a medium resolution chassis in it, take a standard resolution chassis for a standard res game ? Not looking to throw out the tube but hopefully re-use it in a MK cabinet if possible.
Thanks

Strange...because I have a 25" med res chassis and the tube checks out as a med res tube, but yet it has altered beast burn-in..... :confused:

Well... come to think of it... they do have multi and tri res chassis... I am not sure if you're going to find a standard res chassis that will work (might)... but you may be able to find a multi-res chassis that runs medium/low res to work.

Hell, I don't know WTF I am talking about... ignore my "NOPE" because the more I think about it the more i think it may be doable.

It's not a problem using a medium res tube with a lower res chassis. The dot pitch of the tube is just finer. Going the other way will look like ass though....
 
According to what I've read, there's four factors in tube-swapping:
  • Neck socket, both physical layout and pinout
  • Yoke impedance
  • Deflection angle
  • Physical size of the screen

Any tubes on which those four factors match, you can freely interchange tubes and chassis across them.

Again, that's what I've read. That may not be totally accurate, and if you're swapping the yoke too, you also have to deal with the big C word.

There's a fifth factor, shadow mask pitch, that doesn't affect compatibility, but puts an upper limit on the resolution the monitor can display without blurring. This is what makes standard vs. medium vs. VGA vs. "HD" tubes what they are. A tube with a dot pitch calibrated for standard res will work fine on a compatible medium res chassis, but will look blurry (and not in a "defocused" way). Depending on the game, this may be acceptable, but for best results you want a tube with a dot pitch appropriate to the resolution you're running at.
 
Which chassis is there now? The U5000 is a dual-res and can be swapped with the K7400 and U2000 which are both standard-res. Also, the medium-res K7500 was re-released to replace the failing U5000's, but you had to change the yoke.

So, you can probably use the tube, but you may need to change yokes when you change chassis...

I'm going with Matt, here. I've swapped tubes in all way possible with ZERO regard to resolution (as Matt stated, clarity can suffer, depending on which direction you go).

Now, most times you will have to change the yokes.
